v.AU'XII.|IA]."LY AIR VALVE AND FUEL MODIFIER FOR INTERNAL COMBUSTION MOTORS Application led .anuary 4, 1932. Serial No. 584,697.

This invention relates to a device for introducing auxiliary air into the manifold e of an internal combustion motor, and modi- 'of the upper side of plug 14 fying that air by additions of Water, lubricating oil, or other mixtures.

The purpose of the invention is to provide a device whereby auxiliary air can be introduced when the motor is actuated at high speeds and cut oil when the motor is actuated at low speeds, and to provide means whereby the auxiliary air may be combined with lubricating oil, water vapor, or other ingredients as desired, and in adjustable proportions. A further obj ect of the invention is to provide means of the kind indicated, which canY be utilized readily for priming purposes and also for the introduction of carbon remover when desired. Further objects and details of the invention will appear as the description proceeds.

In the accompanying drawing forming a part of this specification-,-

. Figure 1 is a vertical section on the line 1 1 of Fig. 2 through a device embodying one form of the invention;

Figure 2 is a plan view of the device shown irf Fig. 1, parts being broken away;

Figure 3 is a section substantially on the line 3 3 of Fig. 2; and

Figure 4 is a partial section and partial elevation of an alternative device, with parts broken away.

The device shown in Fig. 1 comprises a can 10 provided with a cover 11 which may be secured in place on the can by any suitable detachable means 12. Mounted `upon cover 11 is a valve casing 13. In thelower part of' casing 13 there is a plug 14 having a vertical bore 15 in the upper part of which there is a seat for a ball valve 16. There is also an L-shaped bore 17 from the central portion and opening through one side of the plug. A nipple 18 passes through an opening in casing 13 and is screwed into plug 14 in line with the horizontal portion of bore 17. Nipple 18 may be connected by a pipe 19 to the intake manifold 2O of an internal combustion motor.

Cover 11 is provided with two openings 21 and 22. Into opening 22 there is screwed a pipe 23 which extends downwardly to near the bottom of can 10. Beneath the cover plate there isa baile plate 23 through which there are a plurality of perforations 24. Openings 21 and 22 are provided with covers 25 and 26 pivoted respectively at27 ,and 28, the pivots being shown as the screws which fasten plate 23 to cover 11. The screws may be tightened to such a degree that friction ordinarily holds cover plates 25 and 26 in any position to which they are moved. By means of these cover plates the openings may be uncovered more or less as desired. For convenience each of the cover plates may be provided with a pointer, indicated as 29 and 30, and there m-ay be provided markings on the cover 11 as indicated at 31'and 32, to assist in determining the degree to which the openings 21 and 22 shall be uncovered.

In the upper end of casing 13 there is an electro-magnet 33 having its terminals con- `nected by lead lines 34 and 35 to the electrical system 1n such a way that the magnet is energized when the motor is running at considerable speed, but is not energized when th-e motor is running slowly. The electromagnet may be connected in the generator circuit in series with the cut-out, to accomplish this purpose.

l non-magnetic valve stem 36 extendsv upward through the tube 42 of magnetic metal yof the electro-magnet and through the flaring opening 37 yabove the tub. The lower end of stem 36 is attached to a disc 38 of magnetic metal which forms a valve closing bore 17 when it rests thereon by gravity and closing tube 42 when raised thereagainst by energizing the magnet.

A spring member 39 may be attached to a terminal of the electro-magnet and normally rest adjacent to but out of contact with the other terminal. A cord 40 attached to mem'- ber 39 serves to bring the member in contact with the other terminal and short circuit the electro-magnet and the cord may be independently operable ifV desired, the connection to the choke being convenient as auxiliary air is not desired when the choke is being operated.

In the operation of the device described above, can 10 is filled to a desired degree with liquid 41 which may be lubricating oil .or water or both. Covers 25 and 26 are then adjusted to the desired positions and, the motor connected to intake manifold being in operation the device will remain in operative while the4 motor is running slowly, but when 'suilicient speed is attained by the motor, solenoid 33 is energized and valve 38 rises. Thereupon valve plate 38 contacts tube 42 of the electro-magnet and thereby closes the channel 43 around stem 36, so that the space within casing 13 is closed. AThereupon, when the gases within casing 13 become sufficiently evacuated into the manifold, ball valve 16 is raised and allows air from j above baffle plate 23 to enter casing 13 and pass from thence through bore 17 into the manifold. As this operation continues the air is exhausted from can 10 through openings 24 in the baille plate until air is drawn in through pipe 23 and bubbles up through the oil or water or both in can 10. At the same time some air enters opening 21 and passes directly above the baiiie plate into the lower end of bore 15. The adjustment of cover plates25 and 26 obviously determines the proportion of air which passes directly linto bore l5 from opening 21 to that which enters through opening 22 and bubbles up through the oil or water.

' It will be readily seen that this construction provides a means by which auxiliary air may be supplied when the motor is runningv at high speeds and also the Idesired degree of overhead lubrication can be supplied at the lsame time, adjustment of cover plates 25 and 26 determining the degree of lubrication. It will be further understood that water may be used in place of oil in can 10 in order to supply the desired adjusted amount of water vapor to the motor. Also, if both water and oil are supplied to the can, the airbubbling up therethrough will carry both lubricant and water vapor, the relative amounts dewater. i

The device may also operate to prim-e the motor. With the motor at rest, the valves .are in the position in which they are shown in Fig. 1, and priming fluid may be poured into conical cavity 37 and flow through cylindrical opening 43 around stem 36 into the cavity within casing 13. Thereafter valve 38 may be opened by raising Astem 36, which extends upward through cavity 37 sufficiently to be manipulated for this purpose by the fingers. The priming fluid will then flowA downward through bore 17 'Into the manifold. Such priming uid as is trapped in the upper end of bo'e 15 above check valve 16 is sucked into the manifold as soon as the device isoperated at suicient speed.

When desired, "the apparatus may be employed for injecting decarbonizing fluid into Legame' the motor. If the motor is standing still or i a speed sufficient to energize the solenoid and lift valve38, the valve may be forcibly lowered by means of stem 36 while pouring the decarbonizing Huid into casing 13. v

It will be readily understood that one or both of the air inlets may be connected to the upper part of the radiator if desired in order to add water vapor to the auxiliary air supply, and that one of the air inlets may be connected to the crank case o'r other source of lubricant instead of bubbling the air up through the Voil in the can. In Fig. 4, an alternative form of the device is indicated diagrammatically in which the can is omitted and instead there is a casing 50 provided Ywitn openings 51 and 52, opening-51 being indicated at. 53, and opening 52 being connected to the upper portion of the radiator indicated diagrammatically at 54. Valves 55 and 56' are provided for adjusting the absolute' andthe relative inlet through openings 51 and 52. The control of the auxiliary air from casing 50 to the manifold, in a. device such as shown in Fig. 3, may be the same as disclosed in Fig. 1 for the control of the air from can 10 into the manifold. It will be readily understood that, `with a device such as shown in either Fig. 1 or Fig. 4, either of the openings may be connected to either the crank case or the radiator as desired. Therefore, any preferred combination of air,

water vapor and lubricant can be utilized in In the preferred form ofthe device, the

circuitous route .imposed by the baiiie plate upon the lubricant-carrying air aids in breaking up any sizeable drops of oil carried pending upon the relative depths ofoil and of oil or unvaporized .water entering the space above the baiiie plate is dropped onto A the plate by the air eddying therabove, and

vaporize or atomized, thus insuring that the modifying agent enters the manifold in suitable condition to mix with the fuel.
